SPECIFICATION forming pal-t `of Letters Patent No. 284,87e,date d septmber 11, 1883.

Application ilctl June 16, ISES.4 (No model.)

To all whom/tt may concer/1,.-

Be it known that I, SAMUEL MAXIM, of Wayne, in the county of Kennebcc and State of Maine, have invented a new and Improved Oil-Lamp, of which the following is a full, clear, and exact description.

The object of my invention is to provide a simple and efficient device for preventing the escape or overflow of oil to the outside of the lamp fount or stand, meanwhile providing` for free inlet of air to and outlet of gases from the fount, and guarding against a quick outow ofthe oil at the lampcollar should the lamp be accidentally. overturned.

The invention consists of a special construction of the lamp-collar, by which a support is afforded for a glass or porcelain ring, which ring constitutes an oil-guard by its smooth inner surface, the collar being also made with a chamber back of the screw-thread which receives the threaded nipple of theburner,and the top and inner walls ofthe chamberbeing perf( rated for air and oil passages to and from the fount of the lamp, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure 1 is a side elevation, partly in section, of a lamp fount and burner with my improvements applied. Fig. 2 is a cross-sectional elevation of the lamp-collar before the glass or porcelain oil-guard ring is set therein. Fig. 3 is a cross-sectional elevation of the oil-guard ring. Fig. 4 is a like view of the guard-ring holder and air and oil chamber as disconnected from the collar, and Fig. 5 is a plan view ofthe collar socket-piece.

To the lamp-fount a, which may be of any desired size and style, andv over the usual glass or metal iiange, c', thereof I fit the metal collar Z), which may be a plain ring 5 but I prefer to make it with the inwardly-proj ecting flange or rim c at the top for a shoulder against which the glass or porcelain oil-guard ring d may be held by the flange e of the burner-socket e, as in Fig. l, the flange e being secured to collar b by a soldered joint, or a driving fit of the The main body of the socket e is built up of thin metal rings jointed together in suitablev form; or it may be cast or communicates with the outer air vby a series of 5 perforations, g, in the top or upper wall, which is preferably grooved or concaved at'o to better catch the oil, and with the interior of the oil-fount a by a series of perforations, h, cut in the inner wall of the socket, in which inner wall is formed the screw-thread for receiving the nipple 7c of the lamp-burner Z, as in Fig. l. I I prefer to give the chamber j' a triangular form in crosssection by inclining the outer wall from the flange e', or thereabout, inward and downward to the inner vertical wall of the chamber which it joins below the apertures h, as shown, which construction affords facilities for the application of a substantial body, m, of the usual plaster o r cement, which thus serves not only to secure the socket c to the lampfount, but gives a solid backing or reienforce to the entire collar and socket b e when in place; but the particular forni of the parts'may vary within the scope of my inventionAas, for instance, the flange e may project from the eXA treme top edge 'of the chamber f, as in dotted lines in Fig. 4, and the orifices g h may be round or square holes or curved slots; but the numerous small perforations shown are preferred, as they afford ample inlet of air to the lampfount for promoting a free feed of the oil to the wick, and in case of accidental overturning of the lamp, and the fount ct remaining intact, the escape of oil from the fount through the perforations would be slower, making the lamp safer in use.

To assemble the parts, the glass or porcelain oil-guard cl is placed within the collar b, and the socket e placed and secured by its flange e against the lower edge of guard d. The collar b may now be slipped over the flange a of the fount a and secured in place by the cement m, or otherwise. By securing flange c below the top edge of lsocket e, a recess isv formexi therein to better support the guard-ring d jointly with the upper flange, c, of collar b, or when said flange c is dispensed with; and I would also state th at apertures h may be formed in either the inner or outer walls of chamber j', or at their point of junction with each other, their arrangement depending on tlleshape of the socket c and the manner of securing it to the fount a, any lower end construction of socket e which will afford free communication between chamber f and the interior of the fount being permissible.

The operation of the device is as follows: Any oil carried up the wick and escaping at the outside of burner Z will fall upon socket e, and through perforations g to chamber f, and from thence through perforations h to the fount nf, and the glass or porcelain guard d, rising` above socket e, presents a smooth face, up.

which `the escaped oil cannot climb or flow7 thereby insuring its downward flow within the fount, and the cleanliness of the outer surface ofthe fount and laiiip-l'mse7 avoiding pungent odors, and making vthe lamp more agreeable in use; and by making the ,apertures g h below the burner, free exit of gases from the fou'it is secured without dangerously overheating said gases7 as when they pass 'through the burner and near the flame. l l

I wish it to be understood that the'gu'ardring d would act as well were the chamberjdispensed with-that is to say, if `the upper apertures, g, were alone provided through the socket (1,- but the construction shown 'is preferred, for reasons above stated.-

My improvements may also be applied to lanterns, if desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In an oil-lamp, the combination, with a collar, b, having the inwardly-projected rim c 'at the top, of the burner-socket flange e',

arranged below the top edge of the socket, and y secured to the collar to hold a guard-ring in place, as described.

2. The socket e, constructed with the ange e', chamber j", and apertures g h, and screw-` SAMUEL MAXIDL Witnesses:
